Yintoni umzila?
Ii-routers zisetyenziswa ikakhulu kuthungelwano lwengingqi kunye nothungelwano lwendawo ebanzi.Iyakwazi ukuqhagamshela iinethiwekhi ezininzi okanye iisegmenti zenethiwekhi "ukuguqulela" ulwazi lwedatha phakathi kothungelwano olwahlukeneyo okanye amacandelo enethiwekhi, ukuze bakwazi "ukufunda" idatha yomnye nomnye ukwenza i-intanethi enkulu.Ngelo xesha, inemisebenzi efana nolawulo lwenethiwekhi, ukusetyenzwa kwedatha, kunye noqhagamshelwano lwenethiwekhi.
Yintoni utshintsho
Ukubeka nje, iswitshi, ekwabizwa ngokuba yi-hub yokutshintsha.Umahluko ukusuka kwi-router kukuba unokuxhuma kuhlobo olufanayo lwenethiwekhi, ukudibanisa kunye neentlobo ezahlukeneyo zothungelwano (ezifana ne-Ethernet kunye ne-Fast Ethernet), kwaye zenze ezi khompyutha zenze inethiwekhi.
Inokudlulisa imiqondiso yombane kwaye ibonelele ngeendlela ezikhethekileyo zombane kuzo naziphi na iinodi ezimbini zenethiwekhi eziqhagamshelwe kuyo, ngaloo ndlela inqanda usasazo kunye neengxabano zezibuko kunye nokuphucula ukusebenza kakuhle kokusetyenziswa kwebroadband.
Ukutshintsha okuqhelekileyo kubandakanya ukutshintshwa kwe-Ethernet, ukutshintshwa kwenethiwekhi yendawo yendawo kunye nokutshintsha kwe-WAN, kunye nokutshintsha kwe-fiber optical kunye nokutshintsha kwezwi lomnxeba.
Umahluko phakathi kwe-router kunye nokutshintsha:
1. Ukususela kumbono wokusebenza, i-router inomsebenzi wokudayela obonakalayo, onokunika ngokuzenzekelayo i-IP.Iikhompyuter eziqhagamshelwe kwi-Intanethi zinokubelana ngeakhawunti ye-broadband kwirutha enye, kwaye iikhompyuter zikwinethiwekhi yendawo efanayo.Ngexesha elifanayo, inokubonelela ngeenkonzo ze-firewall.Umtshintshi awunazo iinkonzo kunye nemisebenzi enjalo, kodwa inokudlulisa ngokukhawuleza idatha kwindawo yokuya kuyo ngokusebenzisa i-matrix yokutshintsha kwangaphakathi, ngaloo ndlela igcina izixhobo zenethiwekhi kunye nokuphucula ukusebenza kakuhle.
2. Ngokombono wento yokuthunyelwa kwedatha, i-router inquma ukuba idilesi yokuthunyelwa kwedatha isebenzisa inombolo ye-ID yenethiwekhi eyahlukileyo, kwaye umtshintshi unquma idilesi yokudlulisa idatha ngokusebenzisa idilesi ye-MAC okanye idilesi yendawo.
3. Ukususela kwinqanaba lokusebenza, i-router isebenza ngokusekelwe kwidilesi ye-IP kwaye isebenza kwi-network layer ye-OSI model, enokusingatha iprotocol ye-TCP / IP;iswitshi isebenza kwi-relay layer esekelwe kwidilesi ye-MAC.
4. Ukususela kumbono wokwahlula, i-router inokwahlula i-domain yokusasazwa, kwaye umtshintshi unokwahlula kuphela i-domain yengxabano.
5. Ngokombono wendawo yesicelo, ii-router zisetyenziselwa ukudibanisa ii-LAN kunye namanethiwekhi angaphandle, kwaye ukutshintshwa kusetyenziselwa ikakhulu ukuhanjiswa kwedatha kwii-LAN.
6. Ukusuka kwindawo yokujonga i-interface, kukho i-interfaces ezintathu ze-router: i-AUI port, i-RJ-45 port, i-SC port, kukho ezininzi i-switch interfaces, ezifana ne-Console port, i-MGMT interface, i-RJ45 port, i-fiber optical interface, i-auc interface, vty interface kunye vlanif Interface, njl.
